GAS :BURNER FOR FURNACES.

Application filed .Tune 10,

T0 all whom it may conce/m.:

Be it known that l. CHESTER L. SHARP, a citizen of the United States, and a resident of Lancaster, in the county of Fairfield and State of Ohio, have invented certain new and useful improvements in Gas Burnersfor Furnaces; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in gas burners for furnaces and more particularly to such as are adapted for burning` pro ducer gaaone object of the invention being to so construct the valve construction for the burner as to prevent the accumulation of tar on the valve and its seat.

A further object is to provide a simple burner construction which shall embody provision for effectually supplying air to support combustion; which shall be pre,- vented from clogging at the valve; which can readily be kept clean; in which simple means shall be provided to operate the valve, and which may also be utilized for burning; oil or natural gas instead of producer gas.

`With these and other objects in view, the invention consists in certatin novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying` drawings. Figure 1 is a sectional view of a burner embodying my improvements. Figure 2 is a rear view. Figure 8 is a detail view of the valve and Figures 4 and 5 are views of modications.

In the embodiment of my invention shown in Figure l, the body portion of the burner is indicated at 1 and provides a gas chamber 2 terminating in a nozzle 3, and a valve chamber 4. The burner is also provided with an air chamber 5 over the upper portion thereof and receives air from a suitable source of supply through an inlet 6. It will be observed that the air chamber 5 is disposed over the gas chamber and said air chamber and a portion of the air inlet 6 are divided centrally by a partition 7 and that said air chamber discharges air to be mixed with the nozzle portion of the burner.

The rear portion of the body of the burner is provided with a vertical conduit 8 which provides a gas inlet 9 and this conduit is provided with a flange 10 seated in a suitable Specification of Letters Patent. Pgfgmtgd July 18, 1 Q2g 1921. Serial No. 41.76.629.

receptacle 11 containing a sand seal 12. The con duit 8 and its union with the body of the burner is such as to provide an inclined valve seat 13 for an inclined valve llwhich controls the passage of gas into the burner. The valve 14 may be insertedy into the burner through an opening in a side wall thereof. The body of the burner will preferably be made inv diametrically opposite walls with openings to facilitate the insertion or removal of the valve and these openings are normally closed by doors such as indicated at 15. At one end, the valve is provided with arms 16 projecting at an vangle therefrom and seated against the end wall of the burner in proximity to the lower portion of the inclined valve seat. The rear portion of the body of the burner is made with an opening 17, over which a plate 18 is secured.,- said plate having an opening 19 so shaped that its lower wall will form a tooth 20. kA toothed bar 21 having a handle 22`r passes through the opening` 19 into the gas chamber and at its inner end, this toothed bar is provided with a hook to engage a pin 23 carried bythe rvalve. letl At suitable places in the wall the burner adjacent to the rear portion of the gas chamber7 holes 24 may be provided to permit the insertion of a cleaning tool.

It is well known that producer gas coming in contact with a valve or other part of a burner will leave a deposit of tar, an accumulation Aof which will tend to clog and seriously interfere with the efficient operation of the burner andl its valve. By so arranging` the valve and its seat that they will be disposed in an inclined position, as shown in the drawings, any tar which might become deposited on these parts will at once run back into the producer gas tunnel. lt will be observed that the burner is comparatively short and hence the rear portion thereof in which the valve is located will become highly heated and thus the ready discharge of tar deposits will be facilitated. By mounting the inclined valve 14 in the manner above described. it will, when manipulated by the toothed bar to open it, be raised entirely from its seat and there fore all portions of the latter may be kept clean from tar deposits.

ln addition to tar, soot may accumulate at the valve and to cause the removal of this, the valve may be closed a few times sharply against its seat to jar the soot loose and then the valve will be opened wide and the loosened soot will be blown into the furnace and escape through the stack.

If desired to employ oil or natural gas the valve la may be left closed, the operating bar and plate 18 removed and a suitablepoilor natural gas injector located in position to discharge oil or natural gas through the opening l? into the burner.

Instead of. locating the air chamber over the upper portion of the burner body, I may employ an air chamber extending completely around the forward portion of the burner as indicated at 25 Figure et. This air chamber is divided; by a partition 26 and the rear portion of said chamber is spirally `formed as at 27 and thus the air will be evenly distributed at the nozzle of the burner and will be caused: to make a swirl as it passes through the respective parts of the air chamber.

Instead of forming the air chamber over or around the` body of the burner, I may employ jet devices, such as shown 28 Figure 5 entering the gas chamber in rear ot thev nozzle. In Figure 5 of` the drawing I have shown a single air jet device 28 but it is evident that several of these may be einployed.

Having fully described my invention what I claim as new, and desireV to secure by Letters-Patent, is:

l. In a gas burner of the type specified, the combination of a body portion forming a gas chamber terminating at one end in a nozzle and provided at its, other end with a gas inlet portion said body portion provided therein with a valve seat inclining downwardly toward the gas inlet, a valve to rest on said seat, and means for manipulating said valve.

2. A. gas burner of the type specified having a gas inlet portionformed with an inclined valve seat, an inclined valve to rest on said seat, means for manipulating said valve, and arms projecting from said valve and engaging. a portion of the burner body adjacent to the lower portion of the valve, whereby when the valve is raised it will leave all portions of the seat.

3. In a burner of the type specilied, 'the combination of a body portion having a gas inlet portion provided with an inclined valve seat, an inclined valve to rest on said seat, said body portion having an opening, a plate over said opening having a hole formed to provide a tooth, and a manually operable ratchet bar passing through said hole and adapted to engage said tooth, said ratchet bar being connected with said valve.

et. In a gas burner of the type specified, the combination o'f body portion liorming a gas chamber terminating at one end in a nozzle and provided at its other end with a gas inlet portion provided with an inclined seat, a valve to rest on said seat, means for manipulating said valve, and means for dis` charging air toward the nozzle portion ot the burner.

5. In a burner of the type specified, the combination oit al body portion terminating at itsv 'forward end in a nozzle portion and provided at its rear end with a gas inlet portion having an inclined seat, an inclined valve to rest on said seat, means 'for manipulating said valve, an air chamber over the forward portion of said body portion and extending to the nozzle portion oiE the burner, an air inlet at the other end of said air chamber, and a central partition divi ding said air chamber and air inlet.

In testimony whereof, I have signed this speciiication in the presence of two subscribing witnesses.

CHESTER L. SHARP.
